feat(smartplaylist): add album-level fields for sorting and filtering (#5899)
Smart playlists could only sort by the track-level `dateadded`, which scatters
an album's tracks because every track has its own timestamp. There was no way
to express "newest albums first, tracks in album order".

Adds five fields backed by the album table: albumdateadded, albumdatemodified,
albumduration, albumsongcount and albumsize, so `"sort": "-albumdateadded,
tracknumber"` now works. They filter as well as sort, which also enables rules
like "everything from albums added this month" or "skip singles and EPs".

These need the album table rather than the album_annotation table the existing
album* fields join, so they get their own bit in the join mask. The bitmask
already unions joins from both the expression and the sort fields, so a
sort-only reference pulls in the join for the main query while correctly
staying out of the percentage-limit count query.

No COALESCE default is used. That mechanism exists because an album_annotation
row is genuinely often absent; the album row always exists and song_count,
duration and size are NOT NULL, so leaving the columns bare keeps filters
index-friendly.

albumdatemodified follows the existing track-level `datemodified` naming rather
than the `albumdateupdated` spelling used in the request.

albumreleasedate was considered and rejected: album.release_date is
allOrNothing() over the tracks, so it equals the track-level releasedate when
they agree and collapses to empty when they disagree.
